agent-box — your coding agent in the browser

Work with your agent from anywhere

agent-box gives you a private browser workspace that stays available, even when your laptop is closed.

Open it in any browser

Use a secure link to reach your full workspace from a computer, tablet, or phone. There is nothing to install on the device in front of you.

Pick up where you left off

Keep separate jobs in named sessions and return to them later. Your sessions live on the box, so closing the browser does not close your work.

Choose the agent you prefer

Start with Claude Code or Codex. Sign in once during setup, then use the same browser workspace for future sessions.

Keep access in your hands

The box runs in your cloud account, and saved API keys stay on that box. You decide which services and projects the agent can reach. See how access is protected →

Know the monthly cost

The default AWS setup is $12/month, including storage and a stable browser link. The default Azure setup is about $28/month, depending on region. Delete the deployment when you no longer need it to stop charges.

Bring updates to the right session

Connect supported services so reviews, failed builds, and messages can reach the session handling that work. You do not have to keep checking a dashboard. See how it works →

Create your agent-box password. This browser could not fill one in automatically. If possible, reload this page in a current browser and it will create one for you. To continue manually, choose a password, save it in your password manager, and run caddy hash-password --algorithm argon2id --plaintext '<your password>'. Paste the result into WebPasswordHash on the AWS form. Choose Claude Code or Codex, pick a size, and create the stack. When setup finishes, open WebURL under Outputs and sign in with UserName (default workspace) and the password you saved. Complete the agent's one-time sign-in. If you choose Claude Code, use RemoteControlSession to connect from the Claude desktop or mobile app.

Your AWS browser password was generated in this browser.

Your device's secure random generator made this password here. Save it in your password manager before you launch; it cannot be recovered later. This browser also hashes it locally: the AWS launch link contains only the hash, never the password. Choose Claude Code or Codex, pick a size, and create the stack. When setup finishes, open WebURL under Outputs and sign in with UserName (default workspace) and the password above. Complete the agent's one-time sign-in. If you choose Claude Code, use RemoteControlSession to connect from the Claude desktop or mobile app.

Choose a size for your work. The default 2 GiB setup is $12/month and suits one active agent session. Choose 4 GiB at $24/month for parallel sessions or larger builds. Both prices include the server, storage, a stable browser link, and a generous data allowance. Delete the stack to stop billing. If your IT team needs a custom server size, Spot pricing, or resizable storage, use the advanced EC2 setup.

Launch agent-box on Azure

Choose your resource group and region on the Azure form. The deployment creates the server, network, and stable browser link for you.

Create your Azure browser password. This browser could not generate one automatically. Choose a 16–64 character password, save it in your password manager, and enter it in Web Password on the Azure form. You'll use it with userName (default workspace) to open agent-box in your browser. Leave Authentication Type and Admin Password Or Key at their defaults; Azure generates a separate recovery password. No SSH key is needed, and SSH is off by default. Pick a size and deploy. When deployment finishes, open webUrl. On the Settings page, install and sign in to Claude Code or Codex; agent-box starts your first session for you. If you choose Claude Code, use remoteControlSession to connect from the Claude desktop or mobile app.

Choose a size and region for your budget. The default 4 GiB server, 32 GiB storage, and stable browser link cost about $28/month in westus3; prices vary by region. You can choose another size on the form and grow the storage later. Delete the resource group to stop billing.
